The latest course of High-yield cultivation techniques of Panax Notoginseng

Panax notoginseng is a famous and important traditional Chinese medicine, mainly collecting underground rhizomes as medicinal materials. At present, the main producing area is in Wenshan, Yunnan. Panax notoginseng is mainly used to treat the diseases of hemoptysis and hematochezia. It belongs to ginseng genus of Araliaceae, so it is a precious medicinal material with good efficacy. Now there is a certain amount of time for artificial cultivation, but to cultivate Panax notoginseng, it is necessary to obtain high yield and higher economic benefits. Let's learn about the specific cultivation techniques for high yield.

1. Land selection and preparation

Choose the gentle slope land with a slope of about 10 degrees to plant the best, the gentle slope land drainage is relatively smooth, will not accumulate water, the soil had better be deciduous multi-humus soil, it is best not to plant eggplant fruit vegetables before, and the land that has planted soybeans is the best. Before turning the soil, you can spread grass all over the field and burn the field to disinfect, sterilize and kill insects. Turn over the land and apply 2000 jin of organic fertilizer per mu. Cultivated land, leveled land, to make beds, preferably 1.2 meters wide, long according to the topography

2. Seed and seed disinfection

Every year, a robust mother plant is selected to pick seeds during seed setting, and seed screening leaves the fullest, good color and complete seed storage. Seeds are easy to lose vigor when dried, so it is best to store seeds in clean shade 2 rooms. Soak the seeds in 50-degree hot water for 20 minutes before sowing, soak the seeds in seaweed solution for more than 10 minutes, drain and then sow the seeds.

3. Sowing and raising seedlings

Direct strip sowing, evenly sowing in ditches, covering the soil mixed with organic fertilizer, and then covering straw to maintain soil moisture. It can also be covered with gray film after watering, which has good heat preservation and moisture retention. Watering seedlings every day before emergence, it is best to raise seedlings in the greenhouse, and then the temperature and humidity can be controlled when raising seedlings in the greenhouse. Water less after emergence, divide the seedlings once after the seedlings are complete, remove the weakly diseased seedlings, and water them before transplanting, with a spacing of 15 cm and a row spacing of 20 cm.

4. Field management

Found that weeds must be removed, can not compete for nutrients, Panax notoginseng shallow, easy to expose roots after rain, found to cultivate soil to cover in time. Strong light is not conducive to growth, it is necessary to build a sunshade to plant, but too little light transmission will also lead to disease and poor growth. So the final light transmittance is about 50%. Fertilizer should be applied a small amount for many times, mainly potassium fertilizer and phosphate fertilizer, plant ash can be applied twice in seedling stage, and 30 jin calcium fertilizer can be applied in expansion period. You can pinch off the flowers and moss to reduce consumption. Mainly control blight, blight and mites.

5. Harvest and treatment

In order to meet the sales standard, Panax notoginseng must be harvested, dried and then sold. After harvest, the attached soil must be cleaned, and then the roots of the beard should be trimmed, dried, rubbed and thoroughly dried, or directly dried. Put it in the husk and bury it for a period of time, and the appearance will be shiny.

To cultivate Panax notoginseng for high yield, in fact, it is necessary to do better in the details of the planting process, and then manage it more carefully and thoughtfully, provide the most suitable environmental conditions for growth and development, ensure adequate nutrition and maintain a good growth potential, and then grasp the key period management during the flowering and expansion period.
